The equations of two lines are x - 3y = 6 and y = 3x + 2. Determine if the lines are parallel, perpendicular or neither.
are the parallel?

Question

anonymous · Answer

find the slope of each. second has slope 3 because 
$$y=3x+2$$ looks like 
$$y=mx+b$$

anonymous · Answer

first has slope 
$$-3y=-x+6$$
$$3y=x-6$$
$$y=\frac{1}{3}x-2$$

aroub · Answer

3y=x+6 , y=1/3x+2 and y=3x+2 so the lines are not parallel nor perpendicular so ill say neither

anonymous · Answer

they are not parallel because the slopes are not the same, and they are not perpendicular because their product is not -1

anonymous · Answer

the product  of the slopes is 1, so i guess they were trying to trick you into saying perpendicular but they are not
